  1. 1. Statistical methods in single particle fluorescence microscopy

    Författare :Magnus Röding; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; absolute number concentration; Brownian motion; diffusion; fluorescence microscopy; image analysis; image processing; nanoparticle characterization; particle tracking; Smoluchowski process; nanoparticle characterization;

    Sammanfattning : The aim of this thesis is stochastic modeling and statistical inference in single particle fluorescence microscopy related to the experimental observation of randomly moving particles. A central theme is the use of single particle microscopy for estimation of absolute concentration of nanoparticles performing Brownian motion. LÄS MER

  4. 4. Development of Ultra-fast Biosensors for Detection of Non-electroactive Neurotransmitters

    Författare :Yuanmo Wang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; artificial cell; quantification; stability; deformation; dynamic light scattering; adsorption; amperometry; nanoparticle tracking analysis; enzyme monolayer; glucose oxidase; exocytosis; choline oxidase; acetylcholine; enzymatic activity; acetylcholine esterase; gold nanoparticles; Biosensor;

    Sammanfattning : During neuronal communication neurotransmitters are released through the process exocytosis that occurs on the time scale of sub-milliseconds to milliseconds. Neuronal activity by neurotransmitters that are non-electroactive cannot easily be monitored due to limitations in the temporal resolutions of the sensor probes for these analytes. LÄS MER

  5. 5. Towards specific quantification of exosomes using surface-based sensing

    Författare :Deborah Rupert; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; label-free; surface plasmon resonance.; exosome; binding rate; antibody; concentration; nanoparticle tracking analysis; quantification; liposome; cluster of differentiation 63 CD63 ; diffusion; specific detection; mass transport limited conditions; extracellular vesicles; surface-based biosensor;

    Sammanfattning : When exosomes were first observed in 1967, they were believed to be cell debris until extensive studies demonstrated key biological functionalities related to their composition and formation mechanism. Exosomes are nanometer-sized lipid vesicles of endocytic origin, with a membrane consisting of lipids and proteins and encapsulating a cargo composed of soluble proteins and genetic material. LÄS MER
